First Claim
Patent Images
1. A method for characterization of a block boundary between neighboring image blocks within a spatial scalability enhancement layer wherein at least one of said neighboring image blocks is encoded using inter-layer texture prediction, said method comprising:
- operating a block identifying portion to identify the neighboring image blocks;
characterizing said block boundary between neighboring image blocks identified by said block identifying portion with a first boundary strength indicator when one of said identified neighboring image blocks is determined to be encoded using an intra-prediction mode other than said inter-layer texture prediction.
